CVE-2024-49573 Details
Description
In the Linux kernel, the following vulnerability has been resolved: sched/fair: Fix NEXT_BUDDY Adam reports that enabling NEXT_BUDDY insta triggers a WARN in pick_next_entity(). Moving clear_buddies() up before the delayed dequeue bits ensures no ->next buddy becomes delayed. Further ensure no new ->next buddy ever starts as delayed.
A vulnerability in the Linux kernel's scheduling component has been addressed. The issue arose when the NEXT_BUDDY feature was enabled, causing an immediate warning in the pick_next_entity function. This warning was triggered because the clear_buddies function was not properly timed, allowing some next buddies to become delayed. The vulnerability has been fixed by repositioning the clear_buddies function to ensure that no next buddy remains delayed and that no new next buddy starts off as delayed.
